Title: On-load tap changer
Inventor: TONEGAWA EI
IPC: H01F29/04
Filed: 1980-11-21
Abstract: PURPOSE:To enable to prevent the propagation of an accident even if a vaccum valve can be disconnected, by a method wherein auxiliary contacts are mounted between contacts for a tap selector and vacuum valves, and the contact parting time of the auxiliary contact is controlled. CONSTITUTION:Auxiliary contacts H1 and H2 are mounted between contacts TS1 and TS2 of a tap selector and vacuum valves V1 and V2, respectively. The contact H2 is constituted such that, in the case of switching from a tap TAP1 to a TAP2, after a vacuum valve V3 extinguishes arc, it opens before the valve V2 closes. In the case of changing-over from the TAP1 to the TAP2, if a vacuum breakdown occurs to the valve V1, arc is intermittently produced even if the contact is opened. If the valve V2 is closed under said condition, the taps are shorted, but the contact H1 opens at a point of time preceding a current point of time. This permits the taps to be prevented from shorting. In case a vacuum breakdown occurs in the vacuum valve V3, arc is intermittently generated, but the contact H1 is opened, which results in extinguishing the arc.

Filed: 1982-09-24
Abstract: PURPOSE:To ensure the accurate detection of coordinates through a coordinate detector, by calculating the distance between a stylus pen and a tablet surface and corecting an X and a Y coordinates based on this calculated distance. CONSTITUTION:A sine wave of an axis X or Y having a phase difference from the voltage extracted out of a tablet 7 and processed, i.e., said sine wave is delivered to an amplifier 12 against said sine wave given from the filter 3. Based on this phase difference, a storage counter 14 is actuated, and the X and the Y coordinates are computed from equivalent pulses. While said sine wave is held at an amplitude detector and compared with the set value of a signal processor 15a. The signal level is lower than the set value if space exists between the tablet 7 and a stylus pen 5. Therefore amplification degree is increased for amplifiers 4a and 12a to set the value of a detector 6 larger then the set value. Then the distance between the pen 5 and the tablet 7 is obtained from the information of the amplifiers, and the value is corrected for both X and Y coordinates.
